I’ve used patchworm cleaning kits in my 10/22 for a while now so when I ordered an avenge-x in 177 it was just natural to clean the barrel the same way. I tried putting the line in through the barrel to pull through and was stopped by the internal baffles. Grabbed a plastic straw worked it through the baffles, pushed the patchworm in, pushed in far enough to get through the straw, pulled the straw out and voila the line came though no issues.
hope this helps somebody.
